Anyhow, I found this application hawkeye[^]. This little app can identify object type and invoke different methods/events... I'm trying to achieve the same thing here.

class Program
{
   Array colorValues = Enum.GetValues(typeof(ColorType));
   Polygon[] allPolygons = new Polygon[colorValues.Length * shapeValues.Length];
}

The typical solution is to move the initialization code to the constructor of the class.

class MyClass
{
    Array colorValues = Enum.GetValues(typeof(ColorType));
    Array shapeValues = Enum.GetValues(typeof(ShapeType));
    Polygon[] allPolygons = new Polygon[colorValues.Length * shapeValues.Length];

    public MyClass()
    {
        int index = 0;
        foreach (ColorType color in colorValues)
        {
            foreach (ShapeType shape in shapeValues)
            {
                allPolygons[index] = new Polygon(color, shape);
                Console.WriteLine(allPolygons[index]);
                index++;
            }
        }
    }
}

static void Main(string[] args)
{
    MyClass myClass = new MyClass();
}
